    Abstract :

    The mass-consistent wind field model (MCWFM) is applied to simulate high resolution of 100 m wind fields around the Incheon International Airport (IIA), Korea. In this study, three types of input data, that are the 5-m resolution Digital Elevation Model (DEM) data, model output of Korea Meteorological Administration (KMA)’s operational Local Data Assimilation and Prediction System (LDAPS), and seventeen weather observations around airport, are used to produce three dimensional wind flow for a wind guest event issued at the airport during 3 ? 5 of May, 2016. This model validation is also performed by estimating the wind data at each of the virtually subtracted observation points that make up the Low Level Wind-shear Alter System (LLWAS) in IIA, and then by the results to the their original measurements in turn. Especially, the mean value of the wind speed is 7.9 m/s, which was very similar for the average of 8.4 m/s from the same wind speed measurements, and the R-squared value of the wind speed shows MEWFM presents better estimation of 96.2 % to the observations than LDAPS of 66.9 %.The results show that wind fields computed from the MCWFM are more realistic near the hilly area, and well matched to the measurements at the airport during the extreme weather event. Furthermore, given the production of 100-m resolution three-dimensional wind field data within eight minutes and its further use of input data for high-resolution forecasting models, the MCWFM could be very useful for simulating wind flow in the runway in support of wind hazardous management in airports.
